the outside of the brackets 6, their forward Afi connections are secured carryin The object of this invention is to provide anovel adjustable connecting bar between a front and rear gang, which'when the gangs are parallelly arranged and at right angles to the line of draft, may be moved to its various adjustments without aifecti-ng the parallel position of the gangs,- ;but when the gangs have been angled to the line of draft,

such/ adjustment will give the gangs a greater angled position relative to an angled position attained without the adjustment made. a

The further object is to construct an improved carrying ttrame "for the gangs.

In the accompanying drawings, Figure 1 is a plan view of my improved *harrow showing one setof the gangs angled to the line of draft, and in both setsfthe connectin bar shown dotted in an adjustable pos tion. Fig. 2 is aside elevational view astaken on the line 2-2 of Fig. 1.

The forward draft frame is carriedby the tongue 1,and com'prises a cross-bar 4 bolted to the end of the tongue and having r'eara wardly extending ends -5, draft attachment brackets 6 bolted to the outer side of said ends 5, and diagonal rods 7 having their rear ends extending through and boltedto ends being secured'to the tongue to the outer side of the segment brackets 8 located ad' jacent each side of the tongue, by bolt 9, which also passes through the segment brackets.

The main construction of the grear and front gangs 1s similar, each having an angle support 10 to which downwardly, extending axles ;11 and upon which are mounted a p nrality of earth agitating disks -12.- The connections of the torward gangs between the supports 10 and axles are vertical bars 35, their lower ends being-bolted to journal-brackets 13 and their upper ends bolted to the supports' lOh These connections for the rear gangs are vertical rods 14 having their lower ends connected to the journal-brackets l5, and their upper ends bolted by brackets 16 to supports 10, the pivotal sleeve-brackets 17 being mounted rods 14 :between the supports l0 andamles.

The :front gangs have a pivotal and detaohabl'e connection near their outer ends to the forward draft frame by the ends -5 of the bar 4, said ends having an "opening 18 in their lower face in which a horizontal rigid bolt 19 carried by brackets 13 engages, the ends 5 being provided with detaohable brackets 20 having an elongated slot 21 with an opening 22 at the forward end thereof, and an adjusting bolt 23. With bolt 19 located in slot 21 and the bracket .20 moved to oneend thereof and bolted in an operative position as shown, to detach bar 5, "bolt 23 is loosened and the bracket 20 1no.ved rearward and raised, .bolt 19 passing throughopening22. Brace rods 24 have a pivoted bolt connection with supports 10.}

and a hook connection with brackets 6; 4

Hand levers 25 pivoted to segments 8 by bolt 26, have common thumb-catch engagements with the segments, and a link 27 pivotally connecting their lower ends with the inner bars of the forward gangs.

A seat support 28 bolted to the tongue, carries a seatat its upper end, and is braced by bars .29.

' An arched rod 30 has its forward end pivo'tall "connected to the'end of the tongue and as boltedto its rear end two diverging links 31 which have their rear ends bolted to ,the pivotal brackets 17 and form axle sup- .ports for the rear gangs.

Connectingbars 32 have their rear ends bolted to the pivotal brackets 17 at the outer free ends of the rear gangs, and have their forward ends adjustably connected to the .front gangs to the inner sides of the pivot axes thereof. These adjustable connections are by means of brackets 33 bolted to sup- ;ports 10 and havea plurality of spaced holes 34: arranged in lines st'ruckfrom'a radius with the pivot axesof the rear gangs as a center, the forward ends of connecting-rods 32 being shown bolted in the holes nearest the front supports 10. Since the rear gangs angled postions.

have a substantially rigid connection at their inner ends only to hold them in position and from vertical movement, the outer ends of these gangs through play in the brackets 15, have a vertical movement which allows them to drop at certain times to conform to low spots in the ground level A cross angle bar 36 is bolted to the rear end of rod 30 and to the side links 31, having its extending ends over-reaching the connecting-bars 32 and serving as stop for these bars to limit their upward movement, in other words, to hold the free ends of the gangsv down in a working position when in operation.

To move one set of gangs to an angled position, lever 26 is swung forward swinging the front gang by link 27, on its pivot axis, and which by its connecting-bar 32 swings the rear gang to an angle opposite to that of the front gang, as the'gangs are pivoted at diagonally opposite ends. When a greater difference in angle degree between thetwo gangs in their angled position is desired, connecting-bar 32 is adjusted in holes 34Lto suit, having shown such an adjusted position in dotted lines on the angled set of gangs in Fig. 1. It will be noticed that when the front gang is moved back to its normal posi tion, that the rear gang is parallel therewith regardless of. the adjustment made for the difierence in degree of the gangs in their angled position: This feature is accomplished by the adjusting of the free end of the connectingbar as it is swung on its pivot, with the gangs parallel, thusthe farther it is swung from its position near the support 10, the greater will be the diderence in the angle .of the gangs whenin their l/Vith a frame work as here disclosed the independent working of the gangs is devoid of fixed ri' idit since the forward an s in their connections at their pivots have a certain amount of lateral movement, while the rear gangs as a wholehave lateral move ment from the pivotal support of rod 30, thus making an easy drawing barrow because of the capability of the independent gangs to conform to irregularities of the ground.
